1917 Artillery Luger Id help

[Thantos]

Hello All,
I am trying to gather as much correct information on this Luger I inherited from my father as I can. I have two and this is the Second.

I have found that identifying a Luger correctly is not easy, as everyone seems to interpret thing a little differently. This will stay in the family and be passed down to my sons when the time comes.

Here is what I think I have, and please correct me if I am wrong, especially about the grade or value as I need these for insurance reasons.

A WWI DWM Military Artillery:
Year:1917
Proofs :Unsure on this one
Serial#:3812
Cal:9mm Para.
Land Dia.:8,83
Grade:90%
Value:$3175.00

Thanks Gene
